FRAME Application filed .Tuly 5,

My invention relates to means for framing wall openings, landparticularly to novel means for anchoring metal frames to masonarywalls.

It is customary, as disclosed in numerous earlier constructionsillustrated in `co-pending applications for patent heretofore iiled byme, to provide a metal buck and to anchor the same to a masonry wall bymeans of an anchor having a T-head adapted to engage in a slit in theweb or back wall of the metal frame member. In constructions `of thischaracter, it is customary to mount wood blocks on the frame members inorder to assist in attaching wood trim thereto. In the type of anchorjust described, it is essential that the wood nailing blocks bevstaggered relative to the anchors because of the projection of theanchors in the area occupied by the blocks.

In the type of anchor herein disclosed, this difficulty is avoided andthe block may be placed exactly at the point where the lugs engage theVmasonary wall. This. is preferable in order that the shock incident tothe closing of doors mounted in the opening shall be directlytransmitted to the masonary wall.

The desired result is secured by slitting the tile lugs and constructingthe anchors with laterallyY projecting T-headsfadapted to enter theslits. This construction has the advantages already described and inaddition serves to hold the lugs securely against the mason ary wall.This is a decided advantage and eliminates the possibility of crackingof the plaster at a point around the lugs.

The invention will be more readily understood by reference to theaccompanying drawings, in which- Fig. 1 is a perspective view of a doorframe and assembled lugs and anchors;

Fig. 2 is a side elevation thereof showing the frame in position in awall, and

Fig. 3 is a sectional view on line 3 8 of F ig. 2.

In the drawings, I have illustrated a metal buck of generally channelshape having a web 10, flanges 11 and plaster terminal margins 12. Atintervalsin the length of the channel, I strike out lugs or ears 13 fromthe web of the channel, the lugs extending parallel to the flanges 11and serving as means for positioning and holding the frame relative tothe wall. For convenience, a tile ANCI-IOR.

wall is shown, the tile being of the usual when the trim is secured tothe wood blocks,

the shocks applied to the trim are directly transmited to the wallat thepoint of engagement therewith.

As a means for anchoring the frame, I provide elongated slits 15 in thelugs 13 and utilize anchors consisting of a flat elongated'strip 16which may be apertured as shown, these strips having laterallyprojecting T-heads 17 so arranged that the heads may enter the slitslwith the anchor in a vertical position and to firmly engage therewithby rotating the anchor into4 the position shown in the drawings.Preferably two of such anchors are provided at each anchor point,although one strip having lateral T- heads on its opposite sides may beutilized if desired. In order to securely embed the anchor in the mortarthe head is projected outside of the outer margin of the strip, thusleaving a space indicated at 18 in Fig. 3 within which the mortar may beplaced.

By means of the construction shown, the lugs are securely held againstthe side of the masonary wall and the frame is held by both of the lugsagainst a blow in either direction instead of by one lug only as intheconstruction heretofore proposed.

Obviously the form of the anchor may be varied within rather wide limitsand other changes may be made in the construction shown withoutdeparture from the spirit of my invention.

I claim:

1. In'combination, a metal buck of generally channel shape, aperturedtile lugs projecting rearwardly in line with the ianges of the channel,and anchors adapted to be embedded in the masonry and having portionsadapted to interlock with the apertures in the lugs.

2. In a door frame, the combination of a metal frame member, lugsprojecting rearwarding therefrom and adapted to lie alongside of amasonry wall, said lugs having apertures therein, and anchors adapted tolie between courses of masonry and having laterally projecting portionsadapted to engage in the apertures in said lugs.

3. In a door frame, the combination of a metal buck of generally channelshape in cross section, lugs struck out from said buck and projectingrearwardly in line with the flanges of the channel, said lugs havingapertures therein and anchors adapted to lie between courses of' masonryand havingl laterally projecting portions adapted to enter the aperturesin said lugs.l

il. In combination, a metal buck ot channel shape in cross section7apertured lugs struck out from the web oiP4 said channel and projectingrearwardly in line with the fianges of the channel and anchors adaptedto lie between courses of masonry and having` portions adapted to enterthe apertures in said lugs.

5. In Combination, a metal buck, apertured lugs project-ing therefromand anchors having,` lateral T-head projections adapted to cooperatewith the apertures in said lugs.

6, In combination, a metal buck having tile lugs struck out therefrom,said lugs having elongated apertures therein, end anchors having'lateral =ihead projections adapted to engage in seid apertures.

7. In combination, a metal buck having,` lugs projecting rearwardlytherefrom, said lugs having elongated apertures therein and narrow metalstrips having lateral T-head projections on one side only, adapted toengage in the apertures in said lugs for anchoring` the buck to a walhIn testimony whereof I have aiiixed my signature.
